Fig. 7 is a perspective of the assembling sleeve.

Fig. 8 is a perspective of one of the pressure operated jaws for operating the automatic suction valve.

A frame 1 may be a board or timber rigidly mounted ina horizontal plane. Pillow blocks 2 and 3 are fixed upon the frame 1 in transverse alinement. Bearings 4 land 5 are formed in the tops of the pillow blocks and a guide roller 6 is provided with a spindle 7, and the spindle 7 is mounted in the bearings 4 and 5. In a like manner pillow blocks 8 and 9 are fixed upon the frame 1 in transversealinement. Bearings 10 and 11 are formed at the top of the pillow blocks 8 and 9, a spindle 12 is mounted in theV bearings andk a roller 13 is mounted upon the spindle between the bearings 10 and 11.

Attaching plates 14 and 15 are secured to vthe frame 1 between the rollers 6 and 13.

Posts 16 and 17 extend upwardly from the bearing plates 14 and 15. Bearings v18 and 19 are formed at the upper ends of thev posts 16 and 17 and a juice extractor housing 2O is mounted between the bearings 18 and 19.

A conveyer belt 21 runs over the rollers 13 and 6 in the direction indicated by the arrow 22` said belt being depressed between the rollers 13 and 6 to pass under the housing 20, the lower extremities of the housing 20 being substantially on a level with the centers of the rollers. T he belt 21 is of flexible material such as canvas or leather, and has a continuous series of cleats 23, each of said cleats being curved or concaved from their upper edges and the cleats fitting together side by side so as to form a trough 24 to receive a half a lemon or orange 25 lying in the trough with its flat side upwardly.

The juice extractor'housing 20 comprises members 26 and 27. The members 26 and 27 are circular in cross section or side elevation and cup-shaped in longitudinal section and fit together rim to rim to produce a chamber 28. An automatic suction valve 29 fits and operates in this chamber 28. The member 26 has a straight hollow axle 30 extending through the bearing 18 into the end of the suction pipe 31, and a stuffing box nut 32 fits upon the axle 30 and is screw seated on the end of the suction pipe 31, there being packing 33 around the axle 30 against the end of the pipe 31 to make a stuffing box connection between the suction pipe 31 and the axle 30, and a hollow 34 in the axle 30 leads from the chamber 28 in the housing 20. l A bracket 35-is formed in the hollow 34 and a screw threadedv bearing 36 is formed in the bracket at the axial center of the axle 30.

The member 27 has an axle 37 extending into the bearing 19 in line with the axle 30. A bore 38 extends into the axle 37 from the chamber 28, a supporting casing 39 fits tightly in the bore 38 and extends into the chamber 28. A pin 40 is driven tightly through the shell of the axle 37 and fits in a slot 41 formed through the end of the casing 39 to hold the casing from rotating.

A screw 42 is inserted through the end of the axle 37, through the casing 39, through the chamber 28 and screwed into the bearing 36 to hold the members 26 and 27 together, preferably the head of a screw 42 is recessed into the end of the axle 37.

The automatic suction valve 29 is preferably formed in six radial sections, 43, 44,

' 45, 46,47 and 48, the sections being cut rsmall upon the radial lines 49 so that the Vmatic suction valve 29 have inclined faces 52 and53 fitting the faces 50 and 51.

The chamber 28 has straight sides 54 and atJright angles to the axis parallel With each other and joining with the faces 50 and f 51 and the automatic suction valve 29 has straight faces joining With the faces 52 and 53 to fitthe straight faces 54 and 55.

Bearings 56 extend radially from the inner end of the casing 39. Valve stems 57 are slidingly mounted in these bearings. Expansive coil springs 58 are mounted upon the stems 57 and around the bearings 56 against the periphery of the casing 39. Heads 59 are connected to t-he outer ends of the stems 57 by pins 60, Ythe direction ofthe pins 60 being parallel With'the axis, and the heads 59 are fitted in sockets 61 formed in the members 43 to 48 inclusive through their inner sides and at their centers so that the sections may rock to a limited extent upon the pinsV 60. The outer ends of the springs 58 fit against the innerA faces of the sections Y43 to 48 inclusive, there being one spring and one stem for each section.

Perforations 62 are formed through the lmembers 26 and 27 Vwithin the area covered by the faces 50 and 51, so that when the automatic suction valve 29 is in place the faces 52 and 53 of the valve cover the inner ends of the perforations 62. Pins 63vare driven tightlythrough the member 27 to engage'in slots 64 in the sections 43 to 48 to limit the'inward movement ofthe sections and to hold the automaticY suction valve 29 from rotating. Within the housing. The

vstems 57 extend through the casing 39 and. Y pins 65 are inserted through the inner ends' of the stems 57 to hold the stems from moving outwardly under the tension of the springs 58. l

In order to hold the suction valvef29 collapsed While the housing 20 is being as-' one edge of the band and having a central opening 69. YDiametrically opposed notches ad 71 are formed in the edge of the band 67 opposite the head 68,.said notches being Y comparatively deep.Y A second pair of diametrically opposed notches 72 and 73 Vare formed in the edge of theband 67 a step shallower than the notches 70 and 71, and Y site members, as 43 and 46, are pressed inwardly to their limits and the sleeve 66 moved longitudinally in the casing 39 to bring the stems of the members 43 and 46 into the .notches 70 and 71, then the members 44 and 47 are compressed and the sleeve 66 moved another step to bring the stems of the members 44 and 47 into the notches 72 and 73, and then Ythetwo other members 45 and 48 are compressedand the sleeve moved another step to bring*V the stems of the members 45 and 48 into the notches 74 and 7 5. This Will hold all of the members of the suction valve 29 Vcollapsed While the casing 39 is being placed in the axle 37, and While the housing member 26 is being placed in position, Vand the screvv 42 inserted to hold the housing members 26 and 27 together, then a t'ool may be inserted through the axleY 39 to drive the sleeve 66 farther into the casing 39 vand out of engagement Withthe valve stems 57.

The members 26 and 27 have curved side Y,

and Shanks 82 extend from the ribs into the members 26 and 27, and the ribs and Shanks may be soldered or otherwise rigidly secured to the members 26 and-27.

rllhe ribs 8O and V81 are evenly spaced apart and extend all the Way around the members 26 and 27. 'Suction valve actuating heads 83 are arranged alternately with the ribs 80 and 81 and have actuating teeth 84 extending outwardly, and shanlrs 85 extending through radial openings 86 in the housing 20, and stop lugs 87 and 88 extend laterally from the inner ends of the Shanks 85. The inner end faces 89 of the shanlis 85 engage in seats 90 formed in the periphery of the suction valve 29, there being preferablyV two seats 99 to Yeach member, 43, 44, 45, 46, 47 and 48. Y The Shanks 85 'are long enough so that when the'valveV .member 47, for ini stance, is expanded under the tension of the springs 58,' as in Fig. 5, the head 83 is moved outwardly from the periphery of the housing and the teeth 84 extend beyond the planes' of the 'teeth of the ribs 8O and 81,

and so that when the teeth 84 press upon the peel of the fruit 25 and press the peel'against the belt v21, the ypressure will move the mem-f fruit through the openings.

The outer edges 91 and 92 of the belt 21 extend beyond the cleats 23, and wheels 93 and 94 are iixed upon the axles 30 and 37 and have corrugated faces 95 and 96 to run upon these edges 91 and 92 of the belt 21.

so that the travel of the belt will rotate the wheels 93 and 94 to rotate the juice extractor housing 20, and cause the halves of the lemons or oranges to pass under the juice extractor housing 20, and as the operation proceeds the pressure upwardly on the teeth 84 will operate the suction valve members 43, 44, 45, 46, 47 and 48 successively to open the suction valve 29 at thepoint where the housing is in contact with the fruit and the tension of the springs 58 will hold the other members or' the suction valve 29 closed. Suction is applied to the suction pipe 31 to carry away the juice extracted from the fruit.

A bar 98 is connected at its ends to the bearings 14 and 15 and bows around the rear side or' the juice extractor housing 20 and wires 99 and 100 extend around the juice extractor housing 20 in grooves 101 and 102, and the ends of the wires are secured to the center of the bar 98 by a clamp 103, thereby making a stripper to prevent the fruit from traveling around with the juice extractor housing 20.

Various changes may be made without departing from the spirit of our invention as claimed.

Ve claim:

1. A juice extractor comprising a conveyer; a rotary extractor' housing mounted above the conveyer and having a chamber and perforations leading to the chamber;

means for causing suction from the chamber; and a suction valve mounted in the chamber to be operated by contact with the :fruit upon the conveyer.

2. A juice extractor comprising the combination with a conveyer, forming a trough and adapted to receive a half a lemon or the like with the cut side upwardly.; a rotary housing mounted above the conveyer and having a chamber and perforations leading to the chamber; and a suction valve mounted in the chamber to close the perforations and adapted to be opened by contact with the fruit.

3. In a juice extractor, a rotary housing having a chamber and having perforations leading to the chamber; a sectional valve mounted in the chamber and adapted to close the openings; actuating heads arranged radially in the housing; and having shanks slidingly mounted through the housing to engage the sections of the valve so that pressure upon the heads will move the sections to open the perforations.

4. A juice extractor comprising the com* bination with a conveyer forming a trough adapted to receive and carry half a lemon or the like; a rotary housing mounted to be operated by the conveyer and engage the cut side of the fruit, said rotary housing having a chamber and having perforations leading to the chamber; a sectional suction valve mounted in the chamber and adapted to close the perforations; and means whereby the contact of the housing with the fruit will open the perforations adjacent to the fruit and leave the other perforations closed.

In testimony whereof we have signed our names to this specification.
